Top Questions from OKmarts Buyers
Q: How can I track my shipment's exact location, customs milestones, and estimated delivery hour?
A: Immediately upon dispatch, the platform automatically generates an international tracking link integrated with carriers like DHL, FedEx, or UPS. Real-time API tracking is accessible directly from your OKmarts account dashboard, displaying live transit status, customs clearance progression, and finalized delivery updates.
Q: Can OKmarts issue formalized, compliant proforma invoices and commercial invoices tailored for corporate accounting?
A: Absolutely. Our automated billing system generates itemized Proforma Invoices (PI) and Commercial Invoices containing corporate tax IDs, purchase order (PO) numbers, and explicit company details necessary to satisfy international corporate accounting and auditing standards.
Q: How can I verify that a product on OKmarts is brand new and not "New Old Stock" (NOS) with degraded internal components?
A: Our warehouse management system strictly tracks manufacturing date codes, especially for sensitive components like VFD electrolytic capacitors or rubber seals. We explicitly state product conditions on the listing and can provide batch date codes prior to shipment for critical applications.
